Hold on for a minute.......
It is not a turbine only term! Look in any number of piston engine
manuals and especially with fuel injection for "HOT START PROCEDURES".
It happens generally with high ambient temperatures when the fuel air
mixture ratio is not correct or normal. Each engine will require
different procedures according to the manufacturer.

OK, I didn't think of that. I have very little piston time- in aircraft
anyway...

This is the same term for for apples and oranges though. In a turbine hot
start the risk is damaging the engine. In a piston hot start the risks is
not starting, right? Like flooding a car engine on a hot summer day, or did
I get the wrong idea?

Anyway, you learn something new every day, and I'm glad my explanation made
sense to Peter Maus.

As I said, your explanation was essentially good across the board for
turbines and I couldn't have said it better . I've seen some awesome
examples of hot starts with turbine and one that resulted in a rapid
meltdown of a PT6. I'm glad it wasn't me with my finger on the start!!
Most generally the flawed hot start with piston can result in a dead
battery, or burning up a starter. I've seen at least one fire started
with a starter that got overheated and ignited wires and insulation.
In any case, its wise to know the correct procedures for each and
important to follow them!

"HOT START" for a turbine engine refers to when DURING the start the maximum
turbine inlet temperature has been exceeded. Subsequent inspection is
required prior to flight. In a piston engine a HOT START PROCEDURE tells
you how to start an already hot engine as when you just shut down and are
restarting...like maybe don't pull the choke? The terms for turbins and
piston engines are not comparable.

No argument on that. Perhaps its just a matter of not using the more
correct terminology, or in the right context? An amusing story.....we
were getting an infrequent inspection from the FSDO and one of the
inspectors stuck his head in the cockpit of my Hiller 12ET (Soloy),
looked around and asked where the carb heat control was. I kind of
chuckled at his joke, but it wasn't a joke and he got miffed with me
for laughing!
I didn't bother to try and explain it to him......

Yeah...that reminds me of the time I was working my way through my
Aeronautical college one of the world's greatest aircraft mechanics, and I
was pumping more gas than the Arabs. POURING rain when a woman pulls in and
says" fill it and check the engine and transmission oil". Well, being now,
one of the worlds greatest mechanics, I spent about 10 minutes in the
Pouring Rain looking for her Transmission Dipstick. Now frustrated I walked
around the side of her car, looked in at the now impatient customer and
noticed that she had a Standard Transmisstion! I believe that's called DUMB
and DUMBER??? At least the Fed didn't ask you how many degrees of flap you
use to take off.
